URL: http://svn.apache.org/viewvc?rev=570121&view=rev
Log:
* src/qpid/framing/FrameDefaultVisitor.h:
Visitor for all concrete frame body types.
Override to handle specific bodies (methods or header/content)
and provide default handling for others.
* rubygen/MethodBodyDefaultVisitor.rb:
Visitor for MethodBodies with visit functions that call
virtual defaultVisit(). Override to handle specific methods
and give default behavior for others.
Added:
incubator/qpid/trunk/qpid/cpp/rubygen/MethodBodyDefaultVisitor.rb (with
props)
